.learner.org. annenberg media ♪ when we look at a sunset, we see waves of light energy that have traveled an immense distance to reach our eyes. when we look at an ocean, we see waves of water energy that may have journeyed thousands of kilometers to reach our shores. most waves derive their energy from the wind. as the wind blows over the ocean, some of its energy is transferred to the surface, forming waves that move through the water. and it is in large part the power of these waves that makes the coastal environment such a dynamic place. coastal areas are among the most beautiful and desirable places anywhere on earth. the coast and coastal land forms like this beach are the result of a dynamic interaction between two competing geologic agents-- the rocky land masses and the energy of the ocean. people tend to think of these as separate and independent from one another, but by ignoring the intimate connection between land and sea, they fail to realize that this delicately balanced system is subject to continual change. building walls and boardwalks and homes on a shifting coastline is a gamble w
. we shoot it. we shoot it. i say: why rehearse? let's do it, gang. the camera's rolling. good energy, guys! the camera's rolling. what are you doing now? stand by. scene 7, shot 7, take 1. did they say anything? no. howard. howard. howard, howard, howard. talk to me. talk to me. howard, listen to me. listen to me; listen to me. i want to tell you something. i have no idea what it is. and what i want to tell you is, um ... okay. cut. he forgot his line. i know. but that's okay. i don't give a damn about that. let him, let him go. you catch up. and then come back around for blocking. larry, i don't have lenny. this is just howard. then let's get -- then come this way. is that what you need? action. howard. howard, talk to me. talk to me! talk to me! would you like to listen to me? okay, good. now -- let's cut. i need you to be -- talk to me. talk to me; listen to me. much more aggressive at the top. even higher. talk to me; talk to me. then "okay, listen to me" would be the same -- probably inflection, the same energy. and then, in fact, yeah, yeah, yeah.

. >> and at the small scale, you could use the spherical harmonics to understand how electrons move between energy shells in an atom, for example. so you have orbitals that also use the harmonics of a sphere. >> so we have strings, but not quite string theory. >> no. >> but then we go from electrons, right, and we sort of stop at musical instruments, and then we proceed out to the universe, right? and it's all harmonics. >> yep, it's all there. >> totally cool. >> yeah, it's really cool. >> thanks, liz. >> yep, thank you. >> the greeks' idea of the music of the spheres, the idea that there must be some connection between music and the workings of the heavens, was based on the mystical numerology of philosophers like pythagoras. ironically, even though their explicit declarations of rational orbits analogizing the relative lengths of harmonious strings was wrong, their instinct was correct. while there isn't really a music of the spheres, there is a song of the universe, a steady hum that you hear no matter where you turn your ear, or rather, your microwave detector. that's what robert wilson and a
me but basic terminology that we see drawn out of the tradition of chi- material energy, li- the principle of spiritual energy and together the two combined to be the essence of everything that exists. so, inside me, inside the table, inside everything that's in this room, that's going on, that kind of balance here. mythic; two names it's a vast panorama of scholars, and princes, and kings, and dynasties as you may well know but the two key names that come up in the mythic dimension; in other words the great leaders, if we must have leaders. confucius of course; the great scholar, drawn from his name becomes confucianism and lao tzu the mysterious. some say he didn't even exist; we're not sure when he existed but the composite leader-- and we will have an expert thank goodness on here because i am certainly not one. dr glenn shive will be with us to help us sort through some questions. but i couldn't help but think when we look at the yin yang symbol, i'm sure this is an original insight in terms of chinese religion, but confucius is very much like a yang side with lao tzu a
that calculate the energy flow through our ecosystem from plants, say, to herbivores to carnivores. it's important to understand the effects of species on one another because that is changing quite a bit these days. many species are going extinct due to human activity, and also new species are invading ecosystems due to human activity. ecosystems form much more tightly connected networks than many other networks. what happens is that each species is typically within three links of all other species within the ecosystem. that's a lot closer than, say, the six degrees of separation that is supposed to separate human's familiarity networks, "who knows who" within, say, the u.s. and so these are tight networks where effects on one species can propagate to many other species quite quickly. one of the most famous examples of the effects of one species on the others within the ecosystem through the network that we've been studying is the sea otter example. back in the 1800s, the russians and several other western countries paid native americans to hunt sea otters pretty much to the extinction
